Be it known that we, BERNARD J. HAUSFELD and EDMUND H.LUNKEN, citizensof the United States, residing at Cincinnati, Ohio, have inin WindowConstructions, of which the following is a specification.

Our present invention 'relates to' window constructions for buildings ofthe general style disclosed in applications for Letters Patent oftheUnited States iiled by us September 111,

1903, Serial No. 182,860; and it consists in various improved featuresand inthe construction vand arrangement 0f parts, as will be herein theclaims.

In v the accompanying drawings, Figure 1 shows in perspective aWindowfembodying our present improvements and having its secondabouthorizontally-disposed pivots. Fig. 2 is a similar view ofa window inwhichthe sec-` invention being susceptible of embodiment in this form ofwindow as well as in that shown in Fig. l. Fig. 3 is a horizontalsectional view through a window embodying our invention and-illustratedin Fig. 2, the screen-grooves being omitted'. Fig. 4 is a vertical.sectional view' of the window illustrated in Fig. 2', taken to one sideof the axis of the hinge. v(Figs. 5 and 6 `are detail views showing'howthe sashes may be arranged to counterbalance each other by .gearinginterposed between them.

i and hinged section. Figs. 13 and 14 are perspective views relating tomeans for weighting the sashes and the sash carrying or swingingframes.f f f In the drawings, 1 indicates the main frame, which may be fixed inthewindow-opening in any suitable manner-such, for instance, as isdisclosed in our application, Serial No. 182,860, above referred to,` inwhich said main frame is placed in a casing located within In 'ourpresentinvention we retain the principal features of the'stop mechanismdisclosed inthe applications above' mentionednamely, the stripsextending on each side of the pivots and projecting unequally into thewindow-opening, so that the stops of less pro- 'jection may passone overtheother in' swinging the window through a half-revolution.

One feature of our present invention relates to -means for closing thegroove or space on the inner side of the window lying between the mainframe l and the secondary pivoted frame 2,'so that a practically iushsurface will be presented, a ini'shed appearance will be produced,andthe mainframe and the swinging frame will appear as one and withoutany dividing spacebetweenthemso long f as the swinging frame is-v innormal' position lin the main frame. f n

Referring to Fig. 1, itV willbe seen'that we provide 'a closing orvfinishing strip 3 along the bottom ofthe opening in the'main frame, andthis effect is continued by a strip extending up on either side ofthemain frame, as'v at 3', tothe point 3, which is slightly-'belowl thehorizontalplane of the pivotsof the sec- 1 o nda'ryl frame andwliicliareindicated generallyat the points 4.y Atthe points3adl ditionalclosing-strips 5 are provided; but,iun like the'strips 3', they arepivotally'supported ingstrips are preferably of angle-iron', one

flange, 5, beingfadapted toI lie along the'side'-V edge-of the secondaryframe'- and` the otl'i'e'ry flange, 5" extending from the secondaryframe to the inner edge of the main frame and substantially in the planeof the inner face of the secondary or swinging frame when in normalposition, and thus covering the space which exists between the edge ofthe secondary frame andthe main frame. As will be observed from Fig. 1,the closing or covering strips are arranged at the front of thewindowopening, and therefore their pivots are out of the axial line ofthe journals of the secondary swinging frame, and, further, they arearranged in a lower plane than the said journals. In order to allow thisarrangement of the pivoted closing-strips, we provide slidingconnections between the upper ends of the same and the upper ends of thesecondary frame, formed by slots 6 in the strips through which bolts orpins pass to hold the strips movably to the edge of the secondary frame.As the secondaryiframe swings on its trunnions the pivoted sections 5 ofthe coveringstrips will move therewith while maintaining theirconnections with said secondary frames, and the latter may move throughsubstantially a half-revolution, the pivotal and sliding connectionsjust described allowing this to be accomplished without interference onthe part of the covering-strips. This closing-strip is also used in theform of window shown in Fig. 2, wherein the secondary frame moves aboutvertically-disposed pivots. In this arrangement thefixed part of theclosing-strip extends up one side 3 and across the top and bottom of thewindow to near the middle of the swinging frame, where the hingedsections 5L of the covering-strips are pivoted to the main frame in amanner similar to that described above. These hinged closing or coveringstrips, which extend horizontally, are connected at their free ends tothe swinging frame by means of pin-and-slot connections like thosedescribed above. It will be seen that in both forms of construction thesame result is secured by the fixed and hinged covering-strips* that isto say, covering or closing from View the space or groove locatedbetween the edge of the swinging frame and the main frame. .The closingor covering strips 3 in Fig. 2 are combined, as -shown in Fig. 3, withstopstrips 6, being formed in one piece therewith and of rolled metal.This piece of metal (marked 7) carrying the two strips is secured inplace by rivets 8, as shown, to the main frame,

or when the said rolled pieces are carried by the swinging part of thewindow they are secured thereto as shown at 6. The same construction-c'.e., combining the closing and stop strips on one piece of material-isused in connection with the closing-strip 3 of Fig. 1. In each case thestop fiange or strip is located at one edge of the rolled piece 7 andthe closing iiange or strip at the other edge thereof. The stop-flangescoperate with packed stopstrips 9 9X, composed of channel-iron pieces fstrip.

secured to the fixed or movable frame, as the case may be and asillustrated in Fig. 3.

Referring no\v to the manner of hinging or pivotally supporting theswinging frame and to the particular construction and arrangement of thestop-strips of unequal projection which are associated with the saidhinge, it will be observed from Figs. 7 and 8 that the pivot-trunnionand the socket are arranged independent of thestop-strips. Thesestop-strips we will designate as the hinge stop-strips for conveniencein distinguishing them from those formerly described and which areassociated or coperate with the free edges of the swinging frame. InFigs. 3, 7, and 11, ."indicates the hinge stop-strip which is secured tothe main frame and 10 the hinge stop-strip which is carried by theswinging frame. Each of these stop-strips is composed of a high partmarked 9 and 10', respectively, and each has also a lowpart 9 and 10,and, as in the applications above mentioned, the low parts or those ofleast projection into the windowopening are adapted to engage with thehigh parts or those parts of greatest projection into thewindow-opening, as shown in Fig. 4, and when the secondary frame isswung on its pivots the part 10H of least projection can ride over thelow part 9l of the other stop- Each of the hinge stop-strips is ofchannel form, substantially U shape in crosssection; but the channel ofthe high part faces in the opposite direction from the channel in thelow part of the same strip. The low parts carry packing 11 in theirchannels to contact with the narrow fianges 12 of the high parts oftheopposing stop-strip. Each high part of the hinge stop-strips is providedwith a closing or covering flange 13, which serves to cover or close thespace left between the low part of either hinge stopestrip and theopposing member of the window.

As shown in Fig. 7, we form each hinge stop-strip in sections, which areunited by a v block 12 of right-angular form, fixed by rivets 12H in thechannel of the high section and extending. also 1nto the channel 1n thelow sect1on, where 1t 1s also riveted. The sldc face of the block iscovered with suitable packing or buffer material 14, which preventscontact between the metal surfaces of the fixed and .movable stop-stripsat this point and forms a tight joint when the swinging frame is inclosed position.

We prefer to form the hinge stop-strips@ e., those adjacent thehinge-togethcr with those extending along the adjacent sides of thewindow-all of one piece. This is illustrated in Fig. 11, where it willbe noticed, for instance, that the channel-iron stop-strips 9 are formedof integral continuations of the scction or portion 9 of the hingestop-strip 9, and this same integral construction is present also inconnection with the hinge stop-strip 10", which is extended to providethe chan IOO 55 v that the lowersash can be raised without low-f nelstop-strip 9X. Furthermore, the plates or' pieces Tand. 6', .withtheircintegral closingand-Y4 stops strips, in Fig. 3.maybe formed as anextension of oneofs/the hingestop-stripson the main and swinging frames,and this is-'tr'nef also of Vthe stripv 3 of 1,7.wh'ich rejgirle-V Sentsa part similanin action,arrangement,- `and association. to .thestrip 3%*:As clearly shown in Fig. 11=,it will .benoticed that. the

Referringy to Figs. iand 6-it willbe seen that 'the twof sashes arebalanced means i maintaining a constan-t and effective balancingconnection .with botlv-'th'at is to say, each sash is providedv with..avrack lf3/.fand these mesh with an f, intermediate. pinion 19', .sothat. one sash balances the other. and the balancing-action will not beaffected-when the swinging constant in all the positions of =theswinging' frame.

extend the hollow parting-beadacross the top of the mainframe andproject this down into the window-opening sufficiently far to preventanopening being left here when the lower sash is raised, say, to thepoint shown in'Fig. 4.

.We provide -means V i'ivher'eby the swinging or secondary frame may beweighted, so that 1 an accurate balancing of the said frameon its pivotsmaybe obtained. i For this purpose we 4provide a weight-box composedlofiron pieces` '2li 25, Fig.,14, held by a part ofthe V'swinging.framerandarrangedto' receivev between them the weight-sections' 26.This boXis closed' by La plate :27held in-place by the screwsf28.
